Disclosed is a terminal apparatus and a method for providing media transmission time information in a Push-to-talk over Cellular system. The wear compensating device has a first adjusting device which is arranged on the brake lever and which acts on a stop in such a way that the latter, as an actuating travel delimitation, acts on the first adjusting device and therefore at the same time on the brake lever and defines a corresponding releasing position. The PLL clock generating unit includes an eccentricity correction circuit for correcting the frequency of the reference clock depending on the eccentricity of the magnetic disk.
